To Clear Rose Foliage of Worms. 



63'). Sir, — I have two climbing roses, "Gem of the Prairie" and "Baltimore 

 Belle. " Last year they were infested with the tiny green slug or caterpillar. I used 

 whale-oil soap, in water, with very little benefit ; then strong tobacco-water, with but 

 little better results, only succeeding in keeping my favorites alive, though other roses 

 were clean and healthy. Can you help me from your wisdom store ? I think an insect 

 powder would be more easily applied, if you will say what would be best to use. 



Mrs. F. J. Heath, Ottawa.

Dust the foliage with fine sifted coal ashes or road dust ; it gives the bushes 

 an ugly appearance for a time, but will prove effectual and need only remain on 

 a few days.

Some varieties, as the Bartlett, is too tender to be grown very far north of 

 Toronto ; but others, as the Flemish Beauty, are more hardy. Try Clapp's 

 Favorite, Flemish Beauty, Ostrand's Summer, Oswego Buerre, and Seckel.
